Greylisting should be handled by the MTA , probably by a milter. 
Use an existing milter ( unfortunately perl milters are unstable)
But greylisting as a method is not appreciated by all. If you are doing
it for your own domains mails on a single server that should be
perfectly fine. But at a MX host with multiple servers greylists are a
huge pain to manage and create more problems than solve them. Anyway
with spammers using proper MTA's now greylists are not really that
effective IMHO.
